Fildena Chewable 100 mg, like other medications containing sildenafil citrate, is primarily used to treat erectile dysfunction (ED) in men. It does not directly increase libido or sexual desire. Instead, its primary mechanism of action is to help men achieve and maintain an erection when they are sexually aroused. Sildenafil, the active ingredient in Fildena Chewable 100 mg, works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). By doing so, it enhances the effects of nitric oxide, a chemical naturally produced in the body during sexual stimulation. Nitric oxide helps relax the smooth muscles of the penis, leading to increased blood flow to the area and, subsequently, an erection. While Fildena Chewable 100 mg can help men with ED regain the ability to achieve an erection, it does not have a direct impact on sexual desire or libido. Libido is a complex issue influenced by psychological, emotional, hormonal, and relationship factors. If you have concerns about your libido or sexual desire, it's essential to discuss them with a healthcare provider who can help identify potential underlying causes and offer appropriate guidance and treatment options.
